I ran a 'yum update' on a CentOS based web server. Kernel version stayed the same at 126.96.36.199-2.fc8xen It upgraded a bunch of stuff, including - mysql from 5.0.45 to 5.0.91 apache from 2.2.3 to 2.2.15
I'm finding that my server response time is quite degraded. Web requests that would have completed in .5 seconds are taking over a second. My configuration files for both Apache and Mysql haven't changed.
I'm running on EC2, so I can run the old image and compare. Server processes appear to be the same.
Where should I look first to find out where the kink in the pipe is?
